MANUEL R. RODRIGUES, OFIBROOKLYN', NEW YORK.

MAGNETICALLY-OIPERATED TRIPPING DEVICE.

Application filed January 14, 1911.

To all whom it may concern:

Be it known that I, MANUEL R. RonnIcUEs, a citizen of the United Statesof America, and a resident of Brooklyn in the county of Kings and Stateof New York, have invented a certain new and usefulMagnetically-Operated Tripping Device, of which the following is aspecification, the same being a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to automatic tripping mechanisms for operatingapparatuses of various kinds, as, for example, those wherein it maybecome necessary at times to use a clutch or release lever to disconnecta machine from, or to connect the same with, a source of power, or whereit is desired to throw in, or release, a clutch in automatic machiner orin cases where it may be deemed advantageous to employ an electricswitch which may be adapted to be operated by a circuit changing deviceto open, or else to close, an electric circuit.

\Vith these and other objects in view, the invention consists of asuitable support and a release or operating lever or tripping bar,controlled by a preferably spring controlled locking rock-shaft and alsoby a magnetically actuated device, as an electromagnet.

It further consists of the constructions, combinations, and arrangementof parts whereby a comparatively simple, and efficient and reliabledevice is obtained, as is hereinafter described and also illustrated inthe drawings which accompany and form a part of this specification, inwhich- Figure 1 represents a plan view of an ap paratus constructedaccording to my invention; Fig. 2 is a front elevation of thesame; Fig.3 is a view in section taken on the line 3, 3, Fig. 3; Fig. 4; is a planview of the apparatus the tripping bar being shown in a locked position;Fig. 5 is a front elevation of the latter; Figs. 6, 7, 8 and 9 are viewsin detail representing parts of thelocking mechanism; and Fig. 10 is aview in section taken on the line 10, 10, Fig. 1.

an electro-magnet B in proper position,

ordinarily by the use of screws 1) and a steady-pin b. The plate A alsopreferably carries a lug A and a 'pin a passing through the same, thelatter forming a pivot or hinge for an armature D. A spring (5 isordinarily supported by the armature, as by means of a screw cl, and thearmature also preferably carries a locking tooth or stud (F. A lug apreferably extends inwardly from the plate A and may in some cases serveto sustain a guide pin a in order to regulate any lateral movement ofthe armature that there may be.

E denotes a locking rock-shaft carrying a locking pin or lever c whichshaft is preferably controlled by means of a spring 6 one end of whichordinarily passes through the top of the same, the other extremity beingfastened by the screw a attached to the plate A. A pin a serving to forma bearing for the shaft E is preferably located at or near the lowerpart of the bore or orifice formed in the plate A in which works therock-shaft E which latter is ordinarily constructed with a groove 0 Thinplates H, respectively secured to the support plates A,

A, by screw it, form, in connection with grooves out directly beneaththe same in the support plates A, A, the boundaries of ways orchannelsin which works the reciprocatory tripping bar F, inward lateralmovement of the-said tripping bar being ordinarily prevented by means ofan adjustable guide screw J working in a part a secured to the supportplate A by means of a nut a and washer a The tripping bar F ispreferably formed with an offset or bend F at the outer end of the same,and the said bar has a notch f cut in the same, and it is ordinarilyprovided with impelling means, as a spring Gr encircling the same, whichspring is preferably held between the plate A and the end of the bar Fby means of a pin f and washer I also prefer to use means to prevent thejar of the parts when the bar F is tripped or sprung, as, for instance,the spring Gr encircling the inner end of the said bar and held inposition between the plate A and the said extremity of the bar by meansof the nut f working on The part of the bar F that lies adjacent to theplate A when the said bar is tripped or sprung is preferably providedwith'an insulating strip C set into the same, and intermediate thesupport plates A and A, a pin f is ordinarily attached to the said bar.

P, P, represent the two members of a circuit controlling device of anyordinary or suitable description or conformation, and N, N, are thewires of the circuit which may be supplied with any suitable source ofpower or form of electromotive force, as the battery N The wire Npreferably passes through an orifice a in the plate A, and leads to oneterminal of the coil of the electro-magnet B, the other terminal of thecoil being preferably grounded to the frame of the apparatus. The othercircuit wire U is ordinarily connected with the post M and finger Linsulated by electrically non-con ducting material K and located on thesupport plate A, from which post extends the spring finger L held inposition by a screw Z over an insulator 7c, and which carries at the endof the same a contact pin L which is insulated from the support plate A,as by a strip K of insulating material.

An open circuit organization is disclosed in the embodiment of theinvention shown in the drawings, although it is obvious that my trippingmechanism may be used with either any of the well known open, or closed,or balanced circuit organizations which are now in common use and whichare well known to those skilled in the art.

The operation of the parts of the device position shown in Figs. 4 and 5by pressing the end F of the tripping bar F in an inward position. Theedge of the flat side of the groove 6 of the locking rock-shaft at firstlies against the side of the tripping bar F, as shown in Fig. 7, andremains in this position until the groove f of the tripping barregisters with the groove 6 of the rockshaft and allows. the spring 6 toswing the rock-shaft around inwardly and to carry the locking pin orlever 6 over the inclined part of the wedge-shaped locking tooth or stud(Z the armature D having been meanwhile moved away from the pole of theelectro-magnet B by the impingement of the pin f against the spring d,in consequence of which movement of the parts the rock-shaft is heldfrom rotation by the lever or arm 6 thereof resting against the abuttingedge of the tooth or stop 65 The resilience of the compressed spring Gthen tends to force the tripping bar F in an outward direction and tocause the face of the groove 6 of the rock shaft E to abut the verticaledge of the groove or notch f of the tripping bar F, as shown in Fig. 9,at the same time that the pin 6 rests against the vertical face of thestud 6Z2. Upon the circuit being closed as by the fingers P and P beingcontacted, the current will flow through the wire N to the electromagnetB and thence to the frame of the device and through the tripping bar Fto the contact pin L and to the connection post M, and thence to theother circuit wire N. The electro-magnet becoming thus energizedattracts the armature D and the locking stud (Z springs away from thepin or lever e, whereupon the rock-shaft E becomes freed and allows thetripping bar F to be impelled forward by means of the expansion of thespring G, whereupon the lever 0 will be operated, and may serve toperform any desired function whereby it may be adapted for use in any ofthe different classes of devices set forth hereinabove. When the bar Fis tripped or sprung, the insulating strip C passes in front of the contact pin L and the circuit becomes thereby opened again. When the bar Fmoves in a forward direction upon being released by the action of themagnet, the vertical edge of the notch f, which abuts, as stated, theface of the groove 6 causes the rock-shaft to turn somewhat around thusmoving the lever or arm 0 to the position shown in Fig. 7 which movementputs the spring 6 under more tension in order to allow the latter tooperate the rock-shaft when the bar F is moved inwardly, whereupon thelever or arm 6 is again allowed to contact the stop or tooth (Z the rockshaft being thus controlled by a rearward movement of the trippingmeans.

I wish it to be understood that I do not desire to be limited to theexact details of construction shown and described herein, for variousmodifications within the scope of the claims will occur to a personskilled in the art.
